Riders of the Range.

A growing number of cattle raids prompts the cattlemen to call on their cattlemen's association president Martin Lethbridge to investigate. Sheep Ranchers are suspected, who led by Gregg Randall blame the cattlemen for increased casualties among the sheep herds. Letherbridge falls in love with Randall's daughter, Dolly, and eventually exposes Blunt Vanier as the cause of the conflict.
